    摘要: An insert-molded head harness for use in securing a respirator mask to the face of a wearer, wherein the head harness comprises a web having a central portion and a peripheral portion extending at least partially around the central portion, and a plurality of elastomeric fastening straps having first and second ends, the first ends being integrally bonded to the peripheral portion of the web and the second ends being adapted to be used in securing a respirator mask to the face of a wearer. The head harness can include an elastomeric flange which comprises an elastomeric resin and embeds the peripheral portion of the web. The web preferably comprises a material selected from the group consisting of woven, knitted, and non-woven materials.

    摘要: A respirator 15 has a harness 10 that allows the respirator body 20 to be conveniently disposed beneath a wearer's chin when not in use. The harness 10 includes a substantially flat, flexible strap 14 and an element 12 that contains a curved elongated slot 16. The substantially flat, flexible strap 14 is threaded through the curved elongated slot 16. The curved configuration of the slot 16 causes the flat flexible strap 14 to be deformed to assume the curved configuration of the slot. This deformation of the strap 14 allows the strap 14 to frictionally engage element 12, and the frictional engagement allows the respirator body 20 to be incrementally withdrawn from the wearer's face so that it can be temporarily stored beneath the wearer's chin, and allows the respirator body 20 to be conveniently repositioned over the nose and mouth of the wearer by simply pulling on free ends 34 of each strap 14 and joining a buckle 32 behind the wearer's neck.
